LINER.

Application filed March 3, 1924. Serial No. 696,496.

At the present time there are in common use in printed matter set upon linotype machines lines of fifty-six different widths which are secured by the utilization as one end of the mold of fifty-six liners of different lengths. In addition, the two types of linotype machines in common use today provide different means for holding the liners in position and accordingly the set of liners suitable for use on one type of machine cannot be used on the other type. My invention provides liner means obviating the necessity for the large number of liner parts now required. In the drawings accompanying this specification and forming a part thereof I have shown, for purposes of illustration, one form which my invent-ion may assume. In these drawings:.

Figures l 1 and 1 are together a plan view of the various parts of this illustrative form of my invention Figure 1 showing the base used with the Mergenthaler type of linotype, Figure 1 showing the base used with the Intertype type of linotype, and

' Figure 1 showing the parts used with either base.

Figure 2 is an enlarged view of certain of the parts shown in Figure 1, while Figures 3, 4, and 5 are sections respectively on the lines 3-3, 44, and 5-5 of Figure 2.

The liner means herein shown comprise a base 11 provided with a slot 12 and a guide rib 13 and adapted to be received by the Mergenthaler type of linotype; a base 14 provided with a shouldered slot 15 and an aperture 16 and arranged to be received by the Intertype type of linotype; four intermediate members 17, 18, 19, and 20 respectively 12, 8, 4, and 2 ems in width, each provided with a dovetail tenon 21 adapted to be received in the dovetail slot 22 of the base 11 or of the base 14 or of another of the intermediate members; and

' four end members 23, 24, 25, and 26 respectively 2, 1, 2 and 1% ems in width, each provided with a plain face 27 arranged to form the end of the mold, and each provided with a dovetail tenon 21 arranged to enter any one of the dovetail grooves 22.

By using various of the above parts singly and in combination it is obviously possible to form a liner of any half em length from the liner secured by using the part 24 alone to the liner secured by utilizing the parts 17, 18, 19, 20, and all in series. By utilizing these combinations with either of the bases 11 or 14 it is possible to form th's liner for use on either of the two types of machines now in common use.

Each of the dovetail slots 22 is formed with inclined sides 28 and an inclined back 29 while each of the dovetail tenons 21 is provided with complementarily inclined sides 30 and a complementarily inclined back 31 and accordingly each tenon 21 must be placed in the slot 22 from above, will not pass through, and will serve to support each part of the built up liner from the preceding part so that the entire liner may be picked up by the base part thereof.

The guide rib 13 of the base 11 is not formed integral thereof but is secured by three soft metal pins 32 and similarly the section 38 of the base 14 is not integral with the remainder of the base but is secured thereto by a air of soft metal pins 34. Ae cordingly, wiiile the bases and the liners are held securely in position under normal conditions a portion of each base is adapted to yield upon the imposition of abnormal conditions upon the liner to thus permit the liner to rotate and'escape injury other than the shearing of the soft metal pins which are readily and cheaply replaced.

It will be obvious from the above description that I have provided liner means accom plishing the object of my invention and superior to anything heretofore proposed. It will also be obvious to those skilled in the art that the particular embodiment of my invention herein disclosed may be variously changed and modified without departing from the spirit of my invention or sacrifieing the advantages thereof and that various of the advantageous features herein shown may be used other than in the particular combination of features presented in the embodiment of my invention herein described. It will therefore be understood that the disclosure herein is illustrative only and tha my invention is not limited thereto.

I claim:

1. Liner means comprising a base means arranged to be secured to a liner support, an end means arranged to form one end of the mold, and a plurality of intermediate sections of different lengths formed to be interposed between said end means and said base means in a multiplicity of combinations to psi-I connect said end means to said base means s1 aced a corresponding multiplicity of (litferent distances from said base means.

2. Liner means comprising a supporting part and a supported part separable from each other and connected by a dovetail connection comprising cooperating dovetail members increasing in extent from one face to the other in the direction to cause said supporting part to support said supported part by means of said dovetail connection.

3. Liner means comprising a base member arranged to be connected to the liner support and to carry the liner, normally effective to prevent pivotal movement of the liner relative to said support, but comprising a weakened section arranged to yield to permit such movement upon the imposition upon said liner of a force sutlicient to damage said liner and disposed out of line with the slug-ejecting recess to permit such yielding upon the imposition of such force upon any part of said liner.

at. Liner means comprising a base member arranged to carry the liner proper and to he p'ivotally connected to the liner support, and a part connected to said base normally effective to prevent such pivoting hut arranged to yield to permit such pivoting upon the imposition upon said liner of a force sutlt cient to damage said liner.

5. In combination, a liner arranged to he pivotally connected to the liner support, and a part connected to said liner normally oiled tive to prevent such pivoting; hut arranged to yield to permit such pivoting upon the imposition upon said liner of a force suilicient to damage said liner.

In testimony whereof I hereunto allix my signature.
